ammore-wiens To all whom t mag/concern:

Be it lmovvn that I, Gannon W. Quemar, a citizen of the United States, residing inthe city and county of San Francisco and Stateof California, have invented new and useful lniprovementsin lllindow-Viyipermo whichl the following is .a specification.

This invention relates to Window cleaning devices.

. lt is an object of this invention to provide a means operative at one time on both sides or" a pane of glass in a Window to remove condensed moisture therefrom.

-T he invention 'consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference tof-the accompanying drawing, in Which-- Figure 1 is a perspective view of the device as installed. VFig. 2 is a sectional View of a sash showing the cleaner in elevation. Fig. 3 is a detail sectional viewthrough the Wiper.

2 indicates a pane of glass in a. sash 3 which may be erected in a car, engine cab, pilot house, look-out station, or Sentry box,

v and in which instances it is Very'desirable and necessary that the glass be kept clear of condensed moisture from any source. No diliiculty is experienced as to keeping the inside surface of a Window clear by simply running a hand or a piece of convenient material over it, but this is not as easily done on the outside surface, and, even so, requires the opening of the Window sometimes in a driving rain. By my present invention both sides of the glass are simultaneously cleansed without opening the window and by a single movement of the operator o1' attendant at the station I The device comprises ap'air of'arms 4-5, the former having a short trunnion 6 to project through a hole in the window sash for non-turnable attachment to the adjacent end ofthe companion arm 5. The trunnion is turiiable in the sash and has a screw thread 7 to receive a nut 8 for clamping up the arm 5. The upper ends of the arms 4-5 are laterally off set, as at 9 9, and bent hack at right angles to form parts 10e-l0 which lie close to the sash 3. lVhen trunnloned 1n the sash, the arms lstand out from and parallel with the lglass Q and in the space on each side of and against'l the latter he Wipers, each consisting of a cleaning strip Specification of Lettersetcnt.

11 which may be of any suitable character,

here shown as flat wick folded over a core l2 and clamped in a channel clamp 13. This clamp has spaced pairs of opposite lugs le, v

il against the glass. The slides 16 have reotangular chambers 19 to lit and slide upon. simllarly shaped portions of the arms to hold she wipers irmly toward the glass. ln order that the cleaning, strip may be readily renewed Without dismantling the Whole device, the arms are provided with rounded portions S20-521, the latter being threadedto receive 'a lock-nut 22. By retracting the nut-'22 this allows the lower Slide 16 to move `down onto the round 2% and the upper slide is pulled down hy the clamp i3, which interconnects the slides, throughits relation at the lugs 14 in the sockets. 1Vihen the slides 16 on one arm are at the rounded portions thereof the clamp 13 may then be swung around avv-ay 'from the glass and the strip il removed7 a fresh one inserted and the clamp swung back and forced up to lift the slides along the arm.-

The nut. 22 is lel in a common plane and on opposite sides. of a window glass, they may then beswung' up or down together by the operator, the' Wipers l'bearing, lirmly throughout their lengthen the sides ot the glass. A single sweep over the surfaces serves to etcctually remove the translucent condensation and leave the window clear. To hold the cleaner in one or another of its positions, one or more springs clips 25 may be provided.

Having thus described my invention, what l claim and desire to secure by Letters Patent isi l. In a Window cleaner, a pair or arms adapted to be arranged on opposite sides of a window pane, means to both connect the arms at 'one of their ends and to provide a pivotal mounting for the arms, spaced up; per and lower lateral inwardly extending hollow members onf-the end portions of the arms, a clamp for each arm, said members having interior side pockets, lugs on the clamps extending,1r into the respective poclets, coil springs in the pockets engaged with the lugs to normally force the clamps outcross section, one of the circular cross sec- V tion portions being screw threaded, a pair of lateral member-.s each being formed with an opening t o slidahly receive the arm, said members belng adapted for rotary movement ou the circular cross section only of 'the am, a cleaning element detachably carried by the lateral members,` and a mit member engaged on the threaded portion of the arm for supporting the lateral members on the at side portion of thel arm.

In testimony whereof'l have hereunio set witnesses.
